What indemnity means
You may promise to defend and pay for certain claims against the client — for example if your deliverable infringes someone's IP or causes harm because of your negligence.
One-way vs mutual
Mutual indemnities are fairer when both parties supply materials or rely on each other's work. One-way indemnities that only protect the client deserve scrutiny.
Tying to your control
Indemnity should relate to your actions or deliverables, not the client's misuse of what you built or their unrelated business decisions.
